Fastener weight calculator
Choose the part, size and length to estimate the weight of one piece, a thousand pieces and your whole order.
Estimate for carbon steel (7.85 g/cm³) from nominal dimensions: hex heads to ISO 4017, socket heads to ISO 4762, threads to ISO 724. Real parts vary by a few per cent. Flange heads are calibrated to DIN 6921 catalogue masses, sizes M5 to M12.
ISO 898-1:2013 (mechanical properties) · ISO 18265:2013 (hardness conversion) · ISO 724, ISO 965-1 and ISO 273 (metric threads, tolerances, clearance holes) · ISO 4017, ISO 4762 and DIN 6921 (head dimensions) · ISO 4042:2022, ISO 19598:2016, ISO 10683:2018, ISO 10684, ISO 9717 and ISO 9227 (coatings and salt spray) · AIAG PPAP (capability targets). The results are for guidance; the current edition of each standard and your drawing take precedence.
